LANTERN.

Y SPECIFICATION forming part of `Matters Patentno. 224,703, dated February 17, Isso.V l Application led August 26, 1879.

To all whom it may concern: 1 Be it known that LTHoMAs LANGsToN, of Meriden, in` the county of New Haven and State of Connecticut, have invented anew Im- 5 provement in Lanterns; and I do hereby de- `clare the following, when taken in connection with the accom panying drawing and the letters of reference marked thereon, to be a full, clear, and exact description of the same, which said 1o drawing constitutes part of this specification,

. and represents a sectional side view.

This invention relates to an improvement in that class ot' lanterns known to the tradel as tubular lanterns;7 and it consists in the I5 method of securing the globe in position, as more fully hereinafter described, and particularly recited in the claim.

A is the base, to which the lamp is attached. B B are the tubes or conductors, which lead air downward to aid in supporting combustion. These" tubes are connected at the top by a band, C. D is the globe introduced beneath the band C, and so as to rest on the support E at the base andbe held by the base against transverse movement.

`Within the ring C is-a sleeve, F, fitted so as to have both a vertical and rotating movementwithin said ring, the lower endof said sleeve iitting the neck of the globe D, and so t 3o arranged that when the sleeve F is down upon the globe, as shown, it will hold it (the globe) `upon the base, so as to prevent any movelnent thereof transversely.

ln the ring() is a vertical slot, a, extending from its lower edge upward, and the lower edge of the ring from said slot is inclined, as at d, and may be so inclined in both directions from the slot, as shown.

eis a 'stud projecting from the sleeve F, and

4o in such relative position to the slot a and the inclined lower edge, d, of the ring C that when the sleeve is turned to a position to bring the `stud c beneaththe slot the sleeve` may be raised, as indicated in broken lines, the stud This operation raises the sleeve, so as to allow the introduction or removal ot' the globe, and when the globe is `introduced the sleeve F is pressed down until by turning it the stud e will pass beneath the incline d of the ring O, as shown, and thereby 5o secure the globe in place.

The sleeve F extends above the ring in the form of posts f, and on these the cap or protector G is placed.

The slot a may have a notch, n, into which the stud e Inay be turned when the sleeve is fully raised, as shown; but this is not essential.

There should be a corresponding notch and' incline on the opposite side of the ring `C and 6o a corresponding stud on the opposite side of the sleeve F; but it is not essential.

I do not broadly claim securing the globe of a lantern .by means of a ring forced upon the neck of the globe by a partial rotation 65 and forced vertical movement of said ring, as such, I am aware, is not new; but in such cases the ring has been in the form of a collar turning within the'upper or cap portion of the 1antern,which' in those cases is a stationary 7o or immovable part, whereas in this application the ring is made as a part of the cap and so that the cap and rin gare turned together, the cap forming a convenient means for turning' the ring, and which is the peculiar cbaracteristic of this invention. Neither do l clailn as my invention the air-tubes or means of conducting the air-into the mouth of said tubes, shown in the drawing.

I claim,- 8o

In a lanternthe combination of the basesupport for the globe, the globe, a ring above the globe and concentric with it, connected to the base below the globe, said ring Constructed with a vertical slot, a, and inclined lower edge, d,` with the sleeve F arranged within said ring and so as to set onto the neck ofthe globe, and provided with a projecting stud, e, said sleeve extending up through said ring 4 and attached to or made a part of the cap or 90 protector, substantially as and for the purpose described.
